—What about _____ English-Chinese dictionary on the bookshelf?

—In my opinion, it’s _____ useful tool book for my English learning.

A.a; an             B.an; a             C.the; a            D.the; an

 

【答案】

C

【解析】

试题分析:句意:书架上这本英汉词典怎么样?——我的意见是,对于我的英语学习来说,这是一本有用的工具书。结合语境可知上文特指书架上的工具书,故用定冠词。下文泛指任何一本有用的工具书,故用不定冠词。Useful词首音素是辅音,故不定冠词用a,选C。

考点:冠词

点评:冠词是一种虚词,一般用于名词前面表示特指或者泛指某一个。冠词的应用都用一定规则,熟记这些规则是解题的关键。不定冠词用在名词前,表示泛指任何一个。定冠词用在名词前表示特指某一个。在专有名词及表示泛指的复数名词前一般不要冠词,叫做零冠词。需注意的是不定冠词的用法是看词首音素,不是看首字母,如:useful首字母是元音,但是词首音素时辅音,故不定冠词用a;hour首字母是辅音,但是词首音素是元音,故用冠词an。
